Anatomy education has been revolutionized through digital media, resulting in major advances in realism, portability, scalability, and user satisfaction. However, while such approaches may well be more portable, realistic, or satisfying than traditional photographic presentations, it is less clear that they have any superiority in terms of student learning. In this study, it was hypothesized that virtual and mixed reality presentations of pelvic anatomy will have an advantage over two-dimensional (2D) presentations and perform approximately equal to physical models and that this advantage over 2D presentations will be reduced when stereopsis is decreased by covering the non-dominant eye. Groups of 20 undergraduate students learned pelvic anatomy under seven conditions: physical model with and without stereo vision, mixed reality with and without stereo vision, virtual reality with and without stereo vision, and key views on a computer monitor. All were tested with a cadaveric pelvis and a 15-item, short-answer recognition test. Compared to the key views, the physical model had a 70% increase in accuracy in structure identification; the virtual reality a 25% increase, and the mixed reality a non-significant 2.5% change. Blocking stereopsis reduced performance on the physical model by 15%, on virtual reality by 60%, but by only 2.5% on the mixed reality technology. The data show that virtual and mixed reality technologies tested are inferior to physical models and that true stereopsis is critical in learning anatomy. 相似文献

智能时代,随着大数据、云计算、智能技术等新兴技术在教育领域的应用,衍生出泛在学习、无缝学习、智慧学习等新型学习方式,学习空间作为学习发生的场所也发生着重大改变,其中一个重要的变革趋势是学习空间走向融合。学习空间融合可为学习者构建虚拟和现实无缝融合的环境,使学习者能够轻松、有效和投入地开展正式和非正式学习。文章立足时代背景,对学习空间的主要形态及空间融合的本质内涵进行阐释,指出空间融合具有"教学设计的贯一性"和"学习链条的连续性"两大核心特征,同时指出学习空间存在三种典型的融合样态,分别是物理空间之间的融合、信息空间之间的融合以及物理与信息空间之间的融合。最后,从教与学要素的角度出发提出了目标融合、内容融合、活动融合、场景融合和评价融合五条融合路径,以期为实现学习空间的有效融合提供指导和借鉴。 相似文献

虚拟现实技术在教育中的应用越来越广泛,部分中小学教师已把虚拟现实技术纳入课程设计中,但是课程设计并没有取得预期的效果,因此实现虚拟现实课堂的首要任务是形成一个适用的教学设计模型,在充分发挥虚拟现实技术优势的前提下设计和组织教学活动。文章设计了一种以建构主义学习理论和STEAM教育理念为依托适用于虚拟现实课堂的教学设计模型,且从该模型的理论基础、基本环节、评价机制等方面详细阐述了该教学设计模型的构成要素和基本结构,然后以虚拟现实课程"解码古代建筑的黑科技"为例,具体说明了该教学设计模型的应用,以便给虚拟现实教育探索中的教师提供帮助和建议。 相似文献

混合现实(MR)作为虚拟现实(VR)和增强现实(AR)的高级发展阶段,以沉浸式、跨时空、强交互等特点在教育教学中得到广泛应用。但对国内外文献分析发现,学界对混合现实技术的教学应用效果仍有分歧,对学生学习绩效的影响研究存在较大差异。为探究混合现实技术对学生学习绩效的影响,研究采用元分析方法,对2010-2020年间国内外33项混合现实技术支持下的实验与准实验研究进行量化分析,其总样本量为1460,重点从学段、学科、实验周期和学习场所等调节变量进行深入探析。研究结果表明:混合现实技术对学生学习绩效具有积极的正向提升作用;同时,其应用效果受到学段、学科、实验周期和学习场所等调节变量的影响。依据元分析结论,研究对未来混合现实技术在教育教学中的应用提出了推进学段贯通式MR教学,加快MR与学科融合发展,整合碎片化MR教学资源等建议。 相似文献

Understanding how well teachers integrate digital technology in learning is the subject of considerable debate in education. High Possibility Classrooms (HPC) is a pedagogical framework drawn from research on exemplary teachers’ knowledge of technology integration in Australian school classrooms. The framework is being used to support teachers who teach various stages of schooling to take ‘pedagogical steps’ in their practice with technology. This article focuses on the use of the HPC conceptual framework in a study of seven teachers and their students at two secondary schools in New South Wales, Australia. Analysis confirms the practicality of this conceptual framework for technology integration in secondary school classrooms. This inquiry has implications for addressing the reluctance of teachers to integrate technology in curriculum. The article concludes by suggesting that more schools might consider using conceptual frameworks like HPC to support secondary school teachers to enhance student learning with technology. 相似文献

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes. 相似文献

Adolescent physical inactivity has risen to an alarming rate. Several theoretical frameworks (models) have been proposed and tested in school-based interventions. The results are mixed, indicating a similar weakness as that observed in community-based physical activity interventions (Baranowski, Lin, Wetter, Resnicow, & Hearn, 1997). The theoretical models were decontextualized, thus are unable to address issues central to adolescents' physical activity behavior. In this article, we propose using a theoretical model derived from school-based research on learning behavior change. We review related research on adolescents' physical activity to demonstrate the relevance of using the model to study the dynamic impact of personal, school curriculum, and community variables on adolescent physical activity. We also translate the conceptual model into empirically testable cross-sectional and longitudinal latent growth models and propose concrete steps researchers can take to design empirical studies to examine them. We believe that research studies guided by the proposed conceptual and empirical models will provide useful data for us to better understand the mechanisms of adolescent physical activity motivation and behavior change. 相似文献

The focus of this paper is on the contribution that active touch sensory feedback offered through physical or virtual (with haptic feedback) manipulatives, makes to students' learning through science experimentation. Both theoretical perspectives and empirical evidence are presented. The theoretical perspectives were drawn from two types of theories, namely embodied cognition and additional (touch) sensory channel, which were associated with the use of physical and virtual manipulatives for learning purposes. The empirical evidence was drawn from two different lines of research. The first line of research involves studies that have focused on comparing physical manipulatives and virtual manipulatives (without the provision of haptic feedback), whereas the second involves studies that have focused on comparing virtual manipulatives with and without the provision of touch sensory (haptic) feedback. Both theories supply strong arguments for providing touch sensory feedback during science experimentation, whereas the empirical research outcomes show that providing touch sensory feedback is not always a prerequisite for learning science through experimentation. Those instances for which touch sensory feedback does appear to be a necessity for learning science through experimentation are identified. However, science education studies are limited within the aforementioned research areas. In addition, their findings are inconsistent, especially for the research focused on comparing virtual manipulatives with and without haptic feedback. The latter makes it difficult to arrive at a solid framework that depicts when and how touch sensory feedback should be offered to students for learning science through experimentation. The article concludes with suggestions for future research that would contribute towards development of such a framework. 相似文献
